Air cooler adaptor

Abstract

An adaptor which is positionable within the base of an air cooler and which has L-section flanges extending outwardly and depending therefrom which locate the adaptor with respect to a supporting duct work, the adaptor having retention barbs which snap into and engage surfaces of an air cooler to retain the adaptor in position.

I claim: 
     
       1. An adaptor for supporting an air cooler, said air cooler being of the type having walls extending upwardly from a base and within the cooler perimeter for defining a cool air outlet, said adaptor comprising at least one pair of opposed, relatively fixed panels, each of said pair of panels terminating along its lower edge in an L-shaped flange extending outwardly and downwardly in a direction away from the other of said pair of panels, and each of said pair of panels having outwardly projecting barbs,   the sizes and shapes of said L-shaped flanges and said barbs being such that, when the adaptor supports an air cooler from the upper end of ducting, said flanges overlie and surround said ducting upper end and said barbs engage the walls of said cool air outlet of said air cooler.   
     
     
       2. An adaptor according to claim 1 wherein each said panel comprises an upwardly and inwardly sloping wall, and said barbs extend outwardly from said panel walls, so arranged that, when the adaptor supports an air cooler, the barbs engage surfaces on the walls of said cool air outlet.   
     
     
       3. An adaptor according to claim 2 wherein each said panel slopes more than the outlet walls to which it is adjacent. 
     
     
       4. An adaptor according to claim 2 wherein each said panel terminates at its ends with interengaging surfaces which interengage adjacent ends of adjacent panels to form an assembly. 
     
     
       5. An adaptor according to claim 1 wherein said panels comprise side and end panels, the ends of each of the side panels have upwardly extending surfaces defining respective grooves, and the ends of each of the end panels comprise upwardly extending tongues engageable in respective grooves, and respective resilient fingers which engage over the ends of side panels. 
     
     
       6. An adaptor according to claim 5 wherein a said groove surface at each end of each of said side panels contains an aperture, and each said end panel tongue is provided with a wedge shaped projection which engages the wall of a respective said aperture upon assembly. 
     
     
       7. An adaptor according to claim 5 wherein each end of each said end panel has laterally extending surfaces defining a groove, and each end of each said side panel has a laterally extending lug engageable in a said laterally extending groove upon assembly. 
     
     
       8. An adaptor according to claim 1 further comprising a second pair of opposed panels cooperatively assembled with said first mentioned pair of panels to form a generally rectangular structure, said ducting upper end having a generally rectangular outline and said adaptor being of such dimension that the lower edges of said panels generally coincide with the inner edges of the duct upper end, said L-shaped flanges having a generally horizontal portion configurated to overlie the end face of the wall of said ducting upper end and to support thereon said air cooler, and said outwardly extending barbs engaging upwardly facing surfaces of said cool air outlet wall of said air cooler for detachably locking said adaptor to said air cooler.
